        # Since this class is intended to be used in applications
        # where the top-level event loop is ``io_loop.start()`` rather
        # than ``reactor.run()``, it is implemented a little
        # differently than other Twisted reactors. We override
        # ``mainLoop`` instead of ``doIteration`` and must implement
        # timed call functionality on top of `.IOLoop.add_timeout`
        # rather than using the implementation in
        # ``PosixReactorBase``.
